Study Notes

Chemical messengers coordinate body functions
There are 6 types of chemical messenger systems
Neurotransmitters act locally to control nerve cell functions
Endocrine hormones influence target cells at another location in the body through the blood
Neuroendocrine hormones are secreted by neurons into the blood
Paracrines affect neighboring target cells of a different type
Autocrines affect the same cells that produced them
Cytokines are peptides that can function as autocrines, paracrines, or endocrine hormones
Endocrine hormones are carried by the circulatory system to cells throughout the body
Hormones can affect many different types of cells or specific target tissues
